TYlNG AND BUNDLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 678,138, dated July 9, 1901.

Application filed June 21, 1900.

T at whom it may concern:

Be it known that I, CHARLES SEYBOLD, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Tying'and Bundling Machines, of which the following is a full, clear,

and exact description, reference being had to the accompanying drawings, forming part of this specification.

My improvements relate to machines for tying in bundles folded paper sheets and the like; and it consists of certain improvements in the construction and operation of such machines to be hereinafter particularly pointed out and claimed.

The special object of my invention is to provide means for driving the screw which operates the movable head or follower, so that a single driving-pulley can be employed, rotating always in one direction and acting in conjunction with a pair of friction-clutches either to rotate the screw to move the follower in one direction or to rotate a screw-threaded nut to draw the screw in the other direction.

In the drawings, Figure 1 is a side elevation of my machine with part of the frame broken away. Fig. 2 is a central longitudinal section of the screw-driving mechanism. Fig. 3 is a vertical transverse section on the lines 3 3 of Fig. 1. Fig. 4 is an end elevation of the upper portion of the machine. Fig. 5 is a horizontal section taken on the lines 5 5 of Fig. 3. Fig. 6 is a vertical cross-section on the lines 6 6 of Fig. 1.

The press I have illustrated is a horizontal press mounted in the solid and substantial framework A A, one end of this framework having secured thereto the stationary head B.

O O are three substantial horizontal guiderods securely bolted in the frame for guiding the platen or follower D, mounted to slide thereon horizontally.

Eis the driving-screw, coupled to the platen D in the usual way, so that the movement of the screw as it is advanced or withdrawn will advance or retract the platen D. This screw E for about one-half its length is screw-threaded, while the outer end is smooth, as shown in Fig. 2. 1

Journaled in a suitable journal-box at the inner end of the main frame is a sleeve F, which is screw-threaded for aboutone-half ,m m, secured in the frame.

its length at a and has its middle portion Serial No. 21,056. (No model.)

7 slightly recessed, as shown at b, andthrongh this sleeve, which is screw-threaded at one end, the screw E passes. This sleeve F is formed with a circular flange G at the outer end, provided with ratchet-teeth c on its periphery. Another flange H is also formed on this sleeve, bent at right angles to form the wheel-rim d, and the sleeve is journaled in the frame between these two flanges. Mounted loosely on the inner portion of this sleeve F is a driving-pulley L, the hub of the pulley 6' being extended in both directions to encircle the sleeve, as shown in Fig. 2. M is another sleeve also provided with flanges N and 0; but this sleeve'M is provided with asmooth bore, and the smooth end of the screw E is provided with a longitudinal slot, and the sleeve M carries a key f, which fits in this slot, so that the sleeve and its flanges will rotatewith the screw; but the screw can slide horizontally through the sleeve. The flange N is provided with ratchet-teeth g and flange O with a rim h. This sleeve M is'also journaled in the frame between the flanges N and O.

Keyed to each end of the hub of the driving-pulley L are split-band friction-clutches P, which embrace the rims d it. Either of these bands when expanded will grasp its corresponding rim, and thus couple the driving-pulley to either of the sleeves F or M.

R R are sliding collars mounted on the hub of the driving-pulley and grooved at Z l to receive the rollers a on the bifurcated ends of the friction-clutch levers S S, which are pivoted at about theircentral point on studs These grooved collars R abut against the inner hub-faces n of the pulley L on each side, and the levers by the mechanism to be described are shifted to actuate the lever b to expand its corresponding split band P to couple the proper sleeve to the driving-pulley.

T is a sliding rod extending-horizontally through the frame, and the lower end of the lovers S are bifurcated to embrace this rod at p p.

r r are collars mounted on the sliding rod s is a spiral spring mounted on the rod 1?, bearing against the lower ends of the levers S to keep the sliding collars R normally against the hub of the pulley L. In this way it will be evident that either of the sleeves F or M can be coupled to the drivingpulley.

In order to start or stop the machine, I provide the sliding bar W, which carries the pins i t. This bar W passes through the bifurcation in the lower end of the levers S, and the pins when the bar is actuated strike against the web a on the levers S. This bar W is also provided with an actuating-lever Y, by means of which the bar may be shifted with either of the pins 6 to throw out of engagement the proper lever S, thus disconnecting the clutch between the pulley L and the driving mechanism. A lug w is formed on the platen or follower D, provided with an eye y, through which the bar \V passes, and collars 0, adjustable by set-screws, are provided on this bar IV, so that when the platen or follower D reaches the desired point in either direction the bar \V will be shifted to stop the machine automatically.

From the foregoing description the operation of the screw will be apparent. When the driving-pulley is coupled, as above described, to the rim d of the screw-threaded sleeve F and the screw E is prevented from turning, as will be hereinafter described, the result will be that the screwE will be advanced to advance the follower D. When the other sleeve M is coupled to the drivingpulley, as above described, and the screwthreaded sleeve F is prevented from turning, the screw itself will be rotated to draw the follower D in the other direction. In order to obtain operative results, however, it is essential that when either of the sleeves F or M is coupled to the driving-pulley the other shall be locked from rotating, and in order to accomplish this I provide as follows: Pivoted to the main frame at each end at d e are dogs a B, arranged to engage the ratchet-teeth c and g of the respective flanges G and N on the sleeves F and M. The lower ends of these dogs bear against the horizontal sliding rod D, in which rod notches f g are out. These dogs a B are normally held pressed against this sliding rod D by the spiral springs h t', which are mounted in suitable recesses on the dogs and bear against the sliding arms Z 'm, which slide in these recesses and bear against the pins n p on the frame. The inner collar 7', which is mounted on the sliding rod '1, carries an arm r withv the collar .9, secured to the sliding rod D. In this way the sliding rods T and D are secured together, and they are secured in such a position that when the forward frictionclutch is in operation the lower end of the lever of the dog a will slide into the notch f in the rod D, and when the other clutch is in operation the lower end of the dog D will engage in the notch g in the rod D. When either of these dogs engage the notches in the rod D, the movement is suflicient to cause the upper end of the dog to engage the corresponding ratchet-teeth of the flanges G or N, so that when either of the clutch mechanisms is in operation the other ratchet and sleeve will be locked from movement. In this Way the operating-screw E is always under perfect control and can be actuated in either direction by the same driving-pulley.

Having thus described my invention, what I claim, and desire to secure by Letters Patout, is

1. In a tying and bundling machine the combination, with the follower plate and screw for operating same, of a pair of sleeves, within which the driving-screw is mounted, one sleeve screw threaded and the other keyed to the screw-shaft to allow same to Y slide,a single driving-pulley and a pair of clutches acting between the driving-pulley and the two sleeves, whereby either may be coupled to the driving-pulley to drive the screw, with means for locking the one sleeve when the other is in operation, substantially as shown and described.

2. In a tying and bundling machine, the combination, with the follower plate and screw for operating same, of a pair of sleeves within which the driving-screw is mounted, one sleeve screw threaded and the other keyed to the screw-shaft to allow same to slide, a single driving pulley mounted between the flanges on the sleeves, and frictionclutches between the driving-pulley and the sleeves,whereby either may be coupled to the driving-pulley, ratchet-wheels on the sleeves with dogs to engage same, and mechanism intermediate the clutches and dogs whereby the actuation of either clutch will bring into operation one of the dogs to lock the disconnected sleeve, substantially as shown and described.

3. In a tying and bundling machine, the combination, with the follower plate and screw for operating same, of a pair of sleeves within which the driving-screw is mounted, one sleeve screw threaded and the other keyed to the screw-shaft to allow same to slide, a single driving-pulley mounted between the flanges on the sleeves, and frictionclutches between the driving-pulley and the sleeves, whereby either may be coupled to the driving-pulley, ratchet-wheels on the sleeves with dogs to engage same, operating-lever for actuating the friction-clutches, with rod coupled to said operating-lever normally holding said dogs out of engagement and notches in the rod to operate alternately as the frictionclutches are shifted, substantially as shown and described.
